Common Terminology

� BIM Building Information Modeling

� LOD Level of Detail

� IPD Integrated Project Delivery

� IDP Integrated Design Process

� MEP Mechanical, Electrical & Plumbing

� CAD Computer Aided Drafting

� Prefab Components / systems assembled offsite

Common Terminology – Cont.

� BIM Collaboration� All services working together by utilising BIM as the tool of

communication

� Interoperability� The provision of model data being shared by more than one

stakeholder

� Lean Construction� Maximum value from minimum cost and time, continuous

improvement

� Quantity Takeoff� Model containing material and component quantities

� Clash Detection� Utilising model software to determine clashes between

services and structures

What is BIM

� Short answer

� The construction of a digital model within a virtual environment that enables effective coordination and contains multilayered sub sets of information that can be leveraged by the design / construct and operations team

Software

� Revit

� Complex but powerful

� Additional functions over standard CAD packages

� Design functions

� Autodesk Fabrication Suite

� Allows drawings to be easily translated to manufacturing files

� Navisworks

� Can view a large array of input files

� Is better at clash detection than Revit

� Has a free viewing tool

� Quicker learning curve

Standardising BIM

� NATSPEC

� BIM-MEPAUS

� ANZRS

BIM Evolution

BIM Workflow

Old vs. New Workflow

BIM Team Structure

� The ‘Old Way’ of designing ,constructing and putting

into operation is costly

� The team must be formed early to have impact and

work efficiencies into the project from inception

� Work together to generate the BIM Implementation

Plan, this should also include the client

� Every project is different

Bringing the Models Together

� The Federated Model

� Allows viewing of various formats

� Allows for easier coordination

� Reduction in file sizes

BIM Workflow in Detail

The ‘I’ in BIM

Managing Data

� Too much data can make a model

unmanageable

� Too little – its just a model without a purpose

� Ask yourself:

� What is the data for?

� How is it going to enhance a process?

� Can it be accessed easily?

� Does it need to be accessed offline?

� Who maintains?

Prefabrication / Modularisation

Prefabrication / Modularisation

� Due to the full coordination of all MEP

services, space can be capitalised on

� Parallel manufacturing

� Safer and more controlled working

environment

� Major reduction in material waste and rework

� More rigorous off/on site QA

� Higher commissioning quality

Prefabrication / Modularisation

Prefabrication / Modularisation

Onsite Robotic Point Layout

� Trimble system vastly improves site efficiencies

� Hanger points place on the deck

� Equipment positions

� Penetration locations

� Site Measures

BIM and Improved Productivity

� Data is leveraged and enhanced as the project progresses

� Clashes are typically resolved in the digital environment

� Reworks are dramatically reduced

� Remote access to current and accurate data

� Building status easily tracked

� Progressive handovers / certification / occupancy

Building Operation and

Maintenance

� Building baseline operation verified

� Changes / additions align with intent

� Very detailed assets list

� Automated maintenance process

� Improved building operating costs and conditions

Improves the value of the building

BIM Misconceptions

� BIM is not Revit

� The ‘Mechanical’ contractor runs BIM

� Loss of productivity (on implementation)

� Just follow the BIM Execution / Implementation

Plan

� BIM is too costly to implement

� File sizes are very large

� ‘I have no authority over other trades’

Legal Considerations

� Data IP

� Coordination responsibility

� Overall management of the model

� Who is responsible for the cost of a change

� Accuracy of information and who pays if it is

incorrect

� Who owns the risk (should reap the benefit)

Pictures and Flythrough

Questions/Discussions

� What is your current level of BIM

Implementation?

� What benefits / Issues are there?

� Skills gap – Who / Where
